Patented May 11, 1937 UNITED sTATEs PATENT OFFICE 12 Claims.

This invention relates to siphon bottle heads for use on bottles containing gas charged liquids, such as seltzer water bottles, and has for its objects improved construction in such heads for dispensing the liquid through the head and for filling the bottle therethrough without causing the liquid to be unnecessarily broken up and thereby release an undue amount of its gas contents. Other objects are improved construction making for greater economy in manufacture of the heads and the labor in assembling the same. Still other objects and advantages will appear in the specification and drawing annexed hereto.

In detail, my siphon head comprises a splithollow body of halves I and 2 formed when assembled to provide a through vertical bore enlarged and internally threaded at 3' at the lower end for engaging a threaded split band 4 on the neck 5 of a siphon bottle, the bore walls being shouldered at 6 above the threaded portion 3, and which bore then tapers inwardly and upwardly at l to a reduced diameter portion 9 at the upper end, and a passageway l extends laterally from. the taperedportion through anozzle member II, that turns downwardly at its outer end to open outwardly and downwardly at the downwardly turned outer end of the nozzle member. An inwardly projecting flange I2 is formed around the passageway at the outer end of the nozzle member for a purpose later to be described.

, Fitted within the head is a'liquid conduit I 3 that extends within the passageway from the outer end thereof to the portion 1 of the vertical bore of the body at its inner end, the inner end portion M being of generally bell; shape, with the open end directed downwardly and an outwardly directed flange l being formed around the rim of the bell. This bellportionis formed to generally follow the contour of the tapered walls 1 of the vertical bore within the body, but slightly'spaced from the wall of the bore at the side opposite the juncture between the conduit l3 and bell portion thereof as indicated in Fig. 1. The flange l5 lies below the shoulder 6 and seats at its upper side against the lower surface of the shoulder. I also slightly thicken the upper wall of the bell portion of the conduit at l6 and the conduit itself is of oval cross sectional shape adjacent the bell portion, with its major axis horizontal, and gradually changes in cross sectional shape to circular at the outer endof the conduit, the passageway Ill being similarly shaped so the conduit is supported against the walls of the passageway throughout its length. The conduit I3 and bell portion I4 including the flange I5 is preferably of flexible, chemical resistant material, such as rubber. By chemical resistant, I mean a material adapted to resist the effect of carbonated liquids, such as I seltzer water or the like.

Within the reduced bore portion 9, is mounted a cylindrical block ll adapted to slide vertically therein, which block is horizontally slotted at IE to receive a horizontally disposed cylindrical end IQ of an outwardly and downwardly curved handle that projects outwardly of the body through an opening 2i in the body wall, Said handle is formed with oppositely outwardly extending pins 22 at opposite sides thereof adapted to revolvably fit in holes 23 formed in a pair of ears 24 formed respectively on each of the body halves.

A coil spring 25 is disposed within the bore 9 above block I! and is adapted to react between block i! and a cap 26 that fits over the body at the top of bore 9 and threadedly engages the body at the top to also assist in holding the halves tightly together.

Cap 26 is apertured at 21, and a disk 28 loosely fits across the lower side of the cap and is slidable in bore 9, against which-cap the spring 25 engages at its upper end.

Spring 25, normally forces the block I! downwardly on enlarged portion l6 of the conduit to force the upper wall of the conduit to tightly seat against the upper slightly rounded edge of a tubular member 29 of block tin, which member is formed with an outwardly. projecting flange therearound below the upper end thereof 30 that fits below and against the flange l5 of the bell portion M of the conduit.

Fitted within the block tin member 29 at its lower end and cemented or otherwise suitably secured thereto in extension thereof is a vertical glass tube 3i that extends downwardly from the member to adjacent the lower end of the bottle,

Cir

but slightly spaced at its lower end above the bottom of said bottle and below flange 30 of the member 29 is a rubber gasket 32 that tightly fits between the upper edge of the bottle neck and flange 30, so that when the head is screwed onto the neck band 4 the head is tightly secured to the bottle and sealed against leakage at the neck. Holding the lower end of the head together is a collar 33 threadedly engaging threads 34 formed around the outer side of the head around that portion that is internally threaded at 3, and the halves of the body at the nozzle member are formed respectively with ears 35 that are held together by a screw 36 threaded into openings extending through the ears.

In assembling the head and various elements, I first insert one end of a cylindrical sleeve 31, made preferably of block tin, into the outer end of the conduit [3, the outer sides of the end within the conduit being tapered as indicated in Fig. 1. The sleeve is externally formed with an annular groove therearound midway of its ends, the end of the conduit abutting a shoulder formed around the sleeve slightly spaced from the groove toward the tapered end. The conduit and sleeve are then laid in one of the halves with the flange I2 of the nozzle member fitting within the groove on the sleeve, and the conduit lying in the passageway ID and the bell end of the conduit in the bore of the main body with the flange I5 under shoulder 6. The handle member is laid in place with the end IS in slot [3 in block H and the pin 22 in one of the openings 23, the block I! being disposed in the portion 9 of the bore. The other half of the body is then clamped in place by the collar 33 and screw 36. The body is then screwed onto the bottle neck with washer 32 and members 29, 30 and 3| previously in place as described, thus tightly sealing the head to the bottle and supporting the member 29 with its glass tube 3| in place. The spring 25 is next inserted in the bore 9 and forced to compression by cap 26, which cap also coacts to hold the body halves together. Upon compression of spring 25 the top of the bell portion of the conduit is tightly sealed against the member 29 at the upper rounded edges thereof and the handle 20 is in the dotted position 20 as indicated in Fig. 1. Upon depressing the handle 28, to the full line position (Fig. 1) the pressure of the gas on the liquid in the bottle will force the liquid up tube 3| and will pass through the conduit, since the block I! is raised to permit the upper wall of the bell portion I4 to lift.

It will be seen that the space between the tapered wall of portion 1 of the bore of the body and the wall of bell portion l4 provides for freedom of the bell portion to slightly buckle outwardly upon the block I! moving downwardly to seat the upper wall of the bell portion against the band 29 and the thickened portion it permits considerable compression of the bell wall to insure a tight seal with member 29.

It will be seen from the foregoing that my improved construction enables the use of practically any metal for the head, as brass, bronze, aluminum, ferrous metals or alloys, since the liquid in the bottle during discharge is restricted solely to the glass, block tin and rubber, and the valve, being a part of the main conduit through the head, will open to permit a direct flow of liquid therethrough instead of causing the liquid to pass around ball or poppet valves or to be broken up in passing through variously ported valve members. Also when gas pressure is in the bottle, the rubber conduit is relieved of any unsupported strain caused by the pressure that would tend to cause outward bulging of the conduit under such pressure. The provision of the split head construction enables a much more rapid assembly of the elements and disassembly thereof for replacing parts should replacements become necessary and the clamping of the body halves at the outer end of the nozzle member in itself secures the outer end of conduit i3 securely in position between the body halves and sleeve 31.

The sleeve 31, is provided not only to secure the conduit in position, but in filling the bottles, the sleeve 31 provides a hard fitting for engaging the filling nozzle on filling machines.

It is also to be noted that the underside of the nozzle member H, is free of obstructions and is curved to fit the fingers of the holding hand of the operator, and the handle 20 in all positions extends in a downward and outward direction so as not to injure the palm of the operator in manipulating the valve to eject the liquid.
